SPECIFICATION forming part of Letters Patent No. 367,975, dated August 9, 1887.

Application filed November 2, 1886. Serial No. .1l7,8l4. (No model.)

To all whom, it may concern.-

Be it known that I, MARTIN V. HARPER, of North Yakima, in the county of Yakima and Territory of WVashington, have invented a new and Improved \Vindmill, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved windmill which is simple and durable in construction and very effective in operation,

The invention consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of my improvement, parts of the supporting-frame and the wind-wheel being in section; and Fig. 2'is a plan view of the same.

The upper end of the windmilltower or.

supportingframe A is provided with the uprights 13, united diagonally at their upper ends by the cross-beams O. A beam, D, is placed across the frame A, and forms, in conjunction with the upper cross-beams, C, the support or hearing for the wind-wheel frame E, which consists of the two side bars, F and F, the top and bottom bars, G and G, respectively, and

the vertical central bar, H, which, with the side bar F, forms the bearing for the windwheel shaft I, supporting the wind-wheel J ,of any approved construction.

The pivotal axis of the windwheel frame E is to one side of the vertical central bar,H, and is formed on top by a shaft, K, having its hearing in the cross-beam O, and provided on its upper end with an arm, L, which extendshorizontally and at right angles to the frame E, and carries on its outer end a vane, M, hinged below its center to the said arm L.

The lower bearing of the frame E is formed by a tube, N, secured to the cross-beam D and extending into an aperture in the bottom bar, G. The shaft I of the wind-wheel is formed on one end into a crank, I, connected by the pitman O with the vertical rodl, which connects at its lower end with the machinery to be The head P of the rod 1? has a bearing in the guide Q,secured to the center bar, H.

To the bottom bar, G, and to a bracket,H, of the bar H is pivoted a frame, S, in which is pivotally mountedthe vane T, operated by a cord, U, connected to the center at one edge of said vane,and passing through an aperture in the vertical bar of the frame S, and then through an aperture in the bar F of the frame E, and up to and over a pulley mounted in a suitable bearing, V, secured to the vertical bar H. The cord U is then passed downward and through thetube N to the ground. Y

The frame S is held on pivots, so as to close toward the frameG when the wind'blows very strongly and after the operator has set the vane T toward the wind.

. The operation is as follows: The wind blowing in the direction of the arrow at causes the wheel J to turn, and thus impart a reciprocating motion to the main rod P by means of the crank I and the pitman O. The frames and its vane T stand in their normal position, as shown in Figs. 1 and 2, as long as the wheel J is working regularly with the wind blowing at a moderaterate of speed; butwhen the wind changes to a storm, then the operator pulls on the cord U, which causes the vane T to turn on its axis and face the wind, whereby the frame E is turned on its axis,so that the wind wheel J present-s its rim or edge to the force of the wind. The pivoted vane M on the arm L swings on its hinges according to the strength of the wind, and thus presents more or less surface against the wind, so that when the latter changes to a storm said storm acts against the full face of the said vane, and thus assists the vane T to change the face of the wind-wheel J from the direction of the storm.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination, with the eccentricallyj ournaled frame E, formed of top and bottom bars, G G, having vertical shafts K N, vertical outer bars, F F, intermediate bar, H, out of line with the axis of the frame and having the bracket H, the vertical wind-wheel J, journaled in the bars H F, and a pump-rodin line with the axis of the frame and operating the pump, of the vertical horizontal swinging frame S, pivotally connected at its inner ends to the bracket H and bottom bar, G, the vertical vane T, pivoted between the ends of the horizontal arms of frame S, and the cord U, connected to one edge of said vane, extending to the vertical barof frame S, thence to the bar F and inward to the bar II, and then downward, substantially as set forth.

2. A windmill comprising the vertical horizontally-swinging frame E, consisting of bars G G F F, and the intermediate bar, H, out of line with the vertical shafts or axis of the frame,the vertical horizontally-swinging frame S, connected at its inner end with the'l'rameE
